To cut paper at the end of'a strip as for instance at the edge of abaseboard after a strip of paper beginning at the ceiling corner of aside Wall has been applied by the device, there is shown aknife in theform of a revoluble` disk 52 mounted upon the slotted end of a shaft 58and telescopically carried by a cylindrical socket 54 mounted upon acarriage55. To enable the cutting disk to follow irregularities of theWall, the same is slidable in the socket 54 and retained therein as bymeans `of a pin 56 passing `through the shaft 53 and projecting intoslots 57, 58 in the Wall of the cylinder. y .To force the shaftoutwardly in the cylinder, there is shown a spiral `spring 59 acting incompression between the end of the shaft` and the bottom of socket 54. i

To enable the knifev to be'iused either dur ing travel, as alreadyindicated, or to cut a strip ofpaper longitudinally, the socket 54 ismounted upon a disk 60 which is revoluble about the mounting screw 61.

To hold the disk 60 in its desired position, there are shownretainingmembers, as Aballs 62,63 pressed upwardly to project throughperforations in the `lovver disk 64 of the knife 3Q) carriage as bymeans of spiral springs 65,

66carried in sockets67, 68,Whioh sockets are secured to the disk 64.`

` `In the use of the device when papering-a surface Without openings theknife Will be Ways upon thecurved portion 91 or 92 soasto be at one sideor the other `of the strip to beplaced. i Paste is applied `to the endof the strip of paper which i automatically cut the paper during itsapf-` open'm is then placed againstthe Wall at one end of the space towhich it is tobeapplied and the control valves are opened to allow pasteto be expelled throughV the spray head 27 when the brush is moved toapply the paper tol thel Wall. At the end of Vthe strip as When thebaseboard is reached, the control valve is closed and the crank 90 isrevolved having the cutter 52 in the position shown in Figs. 5, 6, and 7thus causing the cutter to :move across the strip of paper to cut thesame; after Whichthe process may be repeated with the neXtstrip. Y v

1f paper is to be applied adjacent .a wall opening when only a .portionof awidthis needed, the fullwidth of the paper may be applied abovetheopening in the manner alreadydescribed for a full Width str1p,`the

`knife maybecaused to travel to cut oi the above the opening and may becarried osition'opposite thelvertical side of the and by pulling on theappropriate Wire6 or 70 the knife may be turned to the position shown inFig. 1, whereupon as the device is `moved downwardly the knife will piper to a plication.

To revolve the disk 60 upon the disk 64, there are shown a pair offlexible members, as Wires 69, 70 extending from a position alongsidethe handle 10 through guide tubes 71, 72 and through ears 7 3, 74carried by a ange 75 projecting from the socket 54, the ends of theWires being secured to the ange as at 76, see Fig. 6. It will be seenthat by pulling upon the appropriate member 69 or 70, the socket 54 maybe revolved through an are of 90 to place the knife into the desiredposition.`

'To mount the knife movably the disk 64 is shown as provided with lugs77, 78, which engage about ways 79, and to cause the .knife to linclinetoward the brush in the position shown in Figs.1 and 6 a spacing lug 81is shown opposingthe 1ug77 and contactingvvith the opposite side of way79.` i

Tojcause travel of the` thus described carriage upon the ways 79, 80,there is shown a belt 82 which is desirably of the character indicatedin Fig. 2, said belt is shown as at tachedto the carriage bygrip members83, 84,` shown in detail in jFig. 7, and the belt Whichis endless aboutidle pulleys 85, 86, 87, 88 and: about a drive sheave 89 which may be`revolved as by means ofa crank 90 to drive the `belt and thus causetravel of the knife. y y j When using the device upon a side wall theupper` portion' ofwhich is out of reach of theoperatonthe valve 38 maybeclosed and the valve 35'vmay beopened before beginning theapplication` of the paper and the control of.r the paste `Willthen bepossibleby` use of `valve 38 `which is Withinthe reach `of the operatormanipulating the device by using the extension handle 12. When thebottom of the stripfis approached by the valves 3 5 and` 38 `beingopened, the flow of paste may "becut oif by using valve 35 after whichvalve 38 maybe closed preparatory to opening valve 35 for repetition ofthe process."
